After you have decided on what topic you are going to write about on your next article go ahead and make a search on google to see how many authority sites have already written on the topic. Make sure you write on the topic on which not much authority sites have written about so that you can rank easily for that keyword on search engines.

Also you must target long tail keywords so that you can rank easily on search engines. Firstly, what actually is long tail keyword? Long tail keywords are three or more words keywords that are actually related to a specific to a topic that a broad subject.

As for example “weight loss” is a competitive keyword with over 368K search volume. If you want to rank for the search related to this keyword, you should rather try to rank for a long tail keyword like “weight loss diet plan” or “7 day diet plan for weight loss” so that you can rank easily for these keywords as these are less competitive than the short tail keyword.

So while you are using a keyword research tool, you must target a keyword that has decent search volume (number of searches per month for that keyword), is less competitive and is profitable(has high CPC).
